Particle System

An openCL and openGL simulation of movement of millions of particles in space

Performance

• Allocate memory directly on GPU without ever use RAM
• Massive parallel computing through kernel with OpenCl, then pass to OpenGL
• Render up to 3,000,000 particles at 60 FPS (run on standard 4 Core iMac) and 10,000,000 particles at 30 FPS

Features

• Start with either disk (with commend-line flag -s) or square:

• Hue moving with time, key "F" to lock/release hue
• Adjust saturation and value with arrow keys
• adjust background color with keys "QW", "AS" and "ZX" for RGB:

• Mouse scoll-wheel (up-down) to zoom in and out
• Mouse scoll-wheel (left-right) to increase/decrease gravity

• Mouse click to add more gravity points
• Key "C" to release gravity points

• Commend-line arguments to select number of particles
• Key "+", "-" to adjust the size of particles

• Key "E" to stop/resume all gravity (all particles start travelling at current speed)
